IMPRQVEMENT IN HARVESTERS.

Specicationforming part of Letters Patent No.39.0d, dated September 8. 1863; antedaled January 3, 1863.

To all whom it may concern:

Be it known that I, FRANKLIN EWER, of Meudon Center, in the county of Monroe and State of N ew York, have invented certain new and useful'Improvementsin Harvesters and I do hereby declare that the following is afirll and exact description thereof, reference being) .had to the accompanying drawingmmking ing wheel; and the invention consists, first, in

connecting the .finger-beam with the frame off' the machine `by an arrangementof doublejointed coupling-bars and braces, whereby the Y tormer is allowed a free yaction iu adapting itselt' to the sur ace of the ground, and is at the i Same time strongly and frmlybraced second',

in the use of aeha'in ortiexible connection between the inner en d ot' the finger-beam anda crank secured to the frame, having 'at one end a vertical rod, to which is secured a pendulum- -\veight, by which means,when going on a hillside or over ,inclined ground, the. machine is prevented` from tipping over, white at the same time the chain does not interfere with the action of the linger-beam; and, third, iu thefarrangement of 'the cutting device, 'wherebyl the same is prevented l'rom'being clicked or clogged by grass or other substance.

I use an ordinary driving and'snpportingwheel, A, to which is secured, in the 'usual manner, a. frame, B, havinga shaft or tongue, C, for attaching the horses to. With this frame the linger-beam D is connected as follows: 0u the ,rear side of the inner'end ot' the' finger;-A beam is secured a-'socket-beariug, a, and the vforward end of .the inner shoe is formed with a similar bearing, b. These I bearings are lon the line of motion of the machine when in use. 1u the rear bearing rests the joint-end of a eonplingbar,.D, .extending inward and obliqnely' backward, 'and jointed to the frame'of the machine in any'suitable manner, asV represented at c, Fig."2. From the end of this bar -next `the ,i linger-beam extends another 'brace coupling-bar, G, obliquely forward, as shown, the other end being jointed at a suitable position in front tothe frame ou the sitmeline ot' motion with the joint c. I naforward bearing, b, ts the joint end of a similar couplingbar,

F, extending backward obliquely across the' bar-G, to which itis riveted or otherwise fastenedat n, and is inally secured in a similar manner to'the inner end of the bar E, as rep` resented at o. Thus arranged, the ti nger-benin has a fre action to adapt itself tothe inclina tion or inequality ot' the surface of the ground,

as iu any other double|ointed coupling ar'- rangement, with the advantage of being more strongly and vrmly braced.-r Tlie b ar` E, by extending bliquely backward to the rear ot the t`rame,`actsasastil` brace against anybacltpressureof the Enger-beam, and the'bar G, by extending forward t0 the front ot' the frame, acts as a brace in the oppositedirecton against the same movement, while the bar F,being attached to the front of the finger-heartland `ilr'mly connected with both the otherV bars,

serves to stiften them audfto keep the-lingerbeam in Vplace.- rlhe inner'ends et' the bars E and G, by 'being jointed to the fra-me at considerable distance apart, furnish' a strong leverage against any back movementof the lingerbeam'. The whole acts as a firm brace, and the.4 vnger-beam cannot become disartangedgor out of place by any ordinary obstruction. By this arrangement greatstrenfgth is obtainedin proportion' to the amount ot; material used, ena-l bling the lnachineto be made unusually light.

To the inner. vend ofthe uger-beamis secured au upright standard or arm, H, of suitable height audsize for the purpose designed,l

tothe upperend 'of which is jointed or pivoted, atd,'aconnectiugirod, l, extendinginward,a1 1d .Similarlyjointed atf to abearingK, secured` conveniently to the frame o'r in some' equiva- ,-leut manner.' This connecting-rod is on the same line or'l plane'with the verticalV turning motion of lthe finger-beam, so as netto inter'- fere with' the free action 'of the latter as it accommodates itself tothe 'surfaceot' the ground,

and its length is such as to always keep the driving-wheei and frame in a perpendicular position' relatively to` the 'ngeubeam-that is, the uprig-hitjplaneof ,the former at right augles with the plane of th latter. Thus the movement of the former, and at the same time so connected together endbraced as to resist any strain, the whole arranged, combinedfand operating substantially 'as hereinset forth.

" 2. 1n combination with the frame and {ingerbeam, the chain Lor its equivalent,'tho crank g, rod p, and pendulum-weightN, arranged substantially as and for the purpose specified.

` l 4Thecutter-bars P I, rasped, roughened, or provided with pointers on their outer 'surfaees, and having secured between them the knives 'M' i, the latter projecting in therear `thereof' as well as in the` front, and for-mingv the guide inlthe guard-fingers, while the out# ter-bars slide free from contact and` clear the fingers from choking, substantially :1s herein' set forth.

'In witneeu whereof I have hereunto signed my nnmoin4 the presence of two subscribing` witnesses.
